[Ab] Abstract:OBJECTIVE: To systematically review and assess the relationship between particulate matter (PM(10) and PM(2.5)) and children's hospital admissions for asthma, using both time-series and case-crossover analyses. METHOD: The PubMed, Ebsco, Ovid and four Chinese periodical databases were screened for studies related to short-term effects of particulate matter on pediatric asthma hospital admissions published from 1 January 1990 to 31 December 2013.Sixteen studies on PM(10) and 10 studies on PM(2.5) were selected finally for meta-analysis. Relative risk (RR) or odds ratio (OR) and 95% confidence intervals (CI) of asthma hospital admissions per 10 µg/m³ increase of daily particulate matter were obtained from each study. RevMan 5.2.11 was used to test the heterogeneity of the results among the different studies and amalgamat the effect size by fixed or random effect model. RESULT: As the concentration of PM(10) increased per 10 µg/m³, the children's hospital admissions for asthma increased by 1.75%; for PM(2.5), a 3.45% increase for asthma hospital admissions as the concentration increased per 10 µg/m³. By subgroup analysis based on study design, the effect size on both PM(10) and PM(2.5) of case-crossover study's results were higher than time-series analysis. CONCLUSION: The short-term increase of the concentration of PM(10) and PM(2.5) may led to the increase of Children's hospital admissions for asthma, and PM(2.5) will present a higher risk contribution.

[Ab] Abstract:BACKGROUND: This review aimed to summarize existing epidemiological evidence of the association between quantitative estimates of indoor air pollution with early childhood respiratory disease. METHODS: We carried out a systematic literature search of peer-reviewed epidemiological studies undertaken in "westernized" countries that have assessed exposure to indoor pollutants and asthma and wheeze from infancy up to the age of 5. RESULTS: The search, between January 2004 and February 2014 yielded 1840 studies for consideration. Following application of eligibility criteria to titles and abstracts 22 independent studies were deemed relevant for further review. Two additional studies were next identified through examination of the references' lists of these studies. Of these 24 selected studies, 16 adopted a prospective cohort design and 8 were case-control studies. Fourteen studies assessed exposure to bio-aerosols, 8 studies assessed exposure to specific air chemicals and two studies assessed exposure to bio-aerosols and air chemicals. Furthermore, 11 studies examined the association of exposure with asthma and 16 with wheeze. Findings indicate that existing studies have reported contradictory effects of indoor pollutants levels and occurrence of asthma/wheeze. CONCLUSION: Additional research to establish causality and evaluate interventions to prevent disease onset is needed.

[Ti] Title:A novel device for studying weight supported, quadrupedal overground locomotion in spinal cord injured rats.

[Ab] Abstract:BACKGROUND: Providing weight support facilitates locomotion in spinal cord injured animals. To control weight support, robotic systems have been developed for treadmill stepping and more recently for overground walking. NEW METHOD: We developed a novel device, the body weight supported ambulatory rodent trainer (i.e. BART). It has a small pneumatic cylinder that moves along a linear track above the rat. When air is supplied to the cylinder, the rats are lifted as they perform overground walking. We tested the BART device in rats that received a moderate spinal cord contusion injury and in normal rats. Locomotor training with the BART device was not performed. RESULTS: All of the rats learned to walk in the BART device. In the contused rats, significantly greater paw dragging and dorsal stepping occurred in the hindlimbs compared to normal. Providing weight support significantly raised hip position and significantly reduced locomotor deficits. Hindlimb stepping was tightly coupled to forelimb stepping but only when the contused rats stepped without weight support. Three weeks after the contused rats received a complete spinal cord transection, significantly fewer hindlimb steps were performed. COMPARISON WITH EXISTING METHODS: Relative to rodent robotic systems, the BART device is a simpler system for studying overground locomotion. The BART device lacks sophisticated control and sensing capability, but it can be assembled relatively easily and cheaply. CONCLUSIONS: These findings suggest that the BART device is a useful tool for assessing quadrupedal, overground locomotion which is a more natural form of locomotion relative to treadmill locomotion.

[Ti] Title:Visualizing monolayers with a water-soluble fluorophore to quantify adsorption, desorption, and the double layer.

[Ab] Abstract:Contrast in confocal microscopy of phase-separated monolayers at the air-water interface can be generated by the selective adsorption of water-soluble fluorescent dyes to disordered monolayer phases. Optical sectioning minimizes the fluorescence signal from the subphase, whereas convolution of the measured point spread function with a simple box model of the interface provides quantitative assessment of the excess dye concentration associated with the monolayer. Coexisting liquid-expanded, liquid-condensed, and gas phases could be visualized due to differential dye adsorption in the liquid-expanded and gas phases. Dye preferentially adsorbed to the liquid-disordered phase during immiscible liquid-liquid phase coexistence, and the contrast persisted through the critical point as shown by characteristic circle-to-stripe shape transitions. The measured dye concentration in the disordered phase depended on the phase composition and surface pressure, and the dye was expelled from the film at the end of coexistence. The excess concentration of a cationic dye within the double layer adjacent to an anionic phospholipid monolayer was quantified as a function of subphase ionic strength, and the changes in measured excess agreed with those predicted by the mean-field Gouy-Chapman equations. This provided a rapid and noninvasive optical method of measuring the fractional dissociation of lipid headgroups and the monolayer surface potential.

[Ab] Abstract:OBJECTIVE: To describe the prevalence rates of smoking, quitting and passive smoking in different populations on their status of education, occupation and geographic distribution. METHODS: A total of 13 408 residents aged 15-69 from 45 counties through stratified multi-stage cluster sampling from Zhejiang province were selected and surveyed, using questionnaires. Data from 13 326 subjects were used for analysis. Indicators as smoking, current smoking, and secondhand smoke exposure, etc., were calculated by weight on age proportions from the 2010 census. RESULTS: Among the adults aged 15 years and older, there were an estimated number of 12.90 million (29.59%) smokers, with 9.99 million (22.92%)current smokers, 8.45 million (19.38%) daily current smokers. The prevalence rates of smoking were 41.18% for men, 3.69% for women, with 45-54 year-old group the highest (51.66%) for men while the group of 65-69 year-olds was the highest (4.62%) in women. The overall rate of quitting was 22.56%. 40.19% of the smokers had thought about quitting, with the main means as self-restriction (87.59%) in conducting the behavior of smoking cessation. Among those non-smokers at age 15 or older, it was estimated that 67.90% (22.77 million) of them had been exposed to secondhand smoke. SHS exposure was the highest in the indoor workplace (62.84%), among all the venues. Knowledge on tobacco among residents seemed to be relatively poor, with only 31.52% of the population were aware that smoking could cause serious three diseases (stoke, heart disease, and lung cancer). 34.04% of the population were aware that secondhand smoking could cause all the three diseases (heart disease, lung disease, and lung cancer). CONCLUSION: Current prevalence of smoking in males in Zhejiang province remained at a high level, indicating that the publicity programs on the knowledge of smoking tobacco was not strong enough and the task of control smoking should be taken more arduously.

[Ab] Abstract:BACKGROUND: Internal hernias include paraduodenal, pericecal, through foramen of Winslow, intersigmoid and retroanastomotic hernias. These hernias could be either congenital or acquired after abdominal surgery. They account for approximately 0.5-5 % of all cases of intestinal obstruction. CASE PRESENTATION: A 48-year-old female was admitted to casualty with a history of abdominal distension and vomiting of 3 days duration. An abdominal X-ray supine film showed multiple small bowel loops with air fluid levels. On surgery she was found to have a transmesocolic hernia. The defect in the transverse mesocolon was repaired. CONCLUSION: The clinical signs and symptoms of lesser sac hernia are non-specific. These rare lesser sac hernias can be lethal. Therefore, immediate diagnosis and surgery is essential. Although a rare entity, they account for significant mortality form intestinal obstruction. We report an extremely rare case of an internal abdominal hernia through the transverse mesocolon, in a young woman.

[Ti] Title:Effects of particulate matter and antioxidant dietary intake on blood pressure.

[Ab] Abstract:OBJECTIVES: We assessed 2 pathways through which dietary antioxidants may counter adverse effects of exposure to particulate matter less than 2.5 micrometers in diameter (PM2.5) on blood pressure (BP): main (compensatory) and modifying (protective) models. METHODS: We used 2002 to 2003 data from the Detroit Healthy Environments Partnership community survey conducted with a multiethnic sample of adults (n = 347) in low- to moderate-income, predominantly Hispanic and non-Hispanic Black neighborhoods in Detroit, Michigan. We used generalized estimating equations to test the effects of ambient exposure to PM2.5 and dietary antioxidant intake on BP, with adjustment for multiple confounders. RESULTS: Dietary antioxidant intake was inversely associated with systolic BP (b = -0.5; P < .05) and pulse pressure (b = -0.6; P < .05) in neighborhoods closest to major sources of air pollutants. Adverse effects of PM2.5 remained significant after accounting for antioxidant intakes. Exploratory analyses suggested potential modifying effects of antioxidant intake on associations between ambient PM2.5 exposure and BP. CONCLUSIONS: Interventions to improve access to antioxidant-rich foods in polluted urban areas may be protective of cardiovascular health. However, efforts to reduce PM2.5 exposure remain critical for cardiovascular health promotion.

[Ab] Abstract:It has been known for centuries that microorganisms are ubiquitous in the atmosphere, where they are capable of long-distance dispersal. Likewise, it is well-established that these airborne bacteria and fungi can have myriad effects on human health, as well as the health of plants and livestock. However, we have a limited understanding of how these airborne communities vary across different geographic regions or the factors that structure the geographic patterns of near-surface microbes across large spatial scales. We collected dust samples from the external surfaces of ∼1,200 households located across the United States to understand the continental-scale distributions of bacteria and fungi in the near-surface atmosphere. The microbial communities were highly variable in composition across the United States, but the geographic patterns could be explained by climatic and soil variables, with coastal regions of the United States sharing similar airborne microbial communities. Although people living in more urbanized areas were not found to be exposed to distinct outdoor air microbial communities compared with those living in more rural areas, our results do suggest that urbanization leads to homogenization of the airborne microbiota, with more urban communities exhibiting less continental-scale geographic variability than more rural areas. These results provide our first insight into the continental-scale distributions of airborne microbes, which is information that could be used to identify likely associations between microbial exposures in outdoor air and incidences of disease in crops, livestock, and humans.
